I created an alternative using the function imagechar to create a string of an image. The below function below was used to create an image the same height and width of the text string. It is used on my website to mask users email addresses.

If you find that you are getting two characters on the end of your imageString that look like a Y and an upside down L then they're probably representations of CR/LF. Try trim()ing the string before outputting it. (I was sooo sure this was a bug <g>)

// This is a simple function to output text to an image// which is centered (as much as I want to do by eye)// and wrapped// Just remember that all the sizes are guessed// doesn't cut on the space (only on number of characters)// or change color of text, but this isn't for that...function imageCenterString( $imgw, $imgh, $image_text = '', $text_size=5 ){ $im = imagecreate( $imgw, $imgh );

The built-in fonts used to be in latin-2 (iso8859-2) encoding. For some time, they are in latin-1 (iso8859-1) encoding. There is no way to change the encoding at all. If you need to use any other encoding, you have to use TrueType fonts.

Drawing a string as an image is a handy way to disguise an eMail address so spam sniffers can't get it as easily. The only catch to creating a dynamic image with your eMail in it is the eMail to be displayed must be passed via the query string to enable static HTML to use it. So, the eMail must be encrypted slightly in order to not defeat the purpose of not typing your eMail address outright. I wrote the following script to do so:

If the script is called without an eMail address, it outputs a 2x2 transparent image.

To call the script to generate the eMail "user@home.com", the HTML tag would be:

<img src="email.php?addr=moc[dot]emoh[at]resu">

To 'encrypt' the eMail address to pass to the script, write the address backwards and replace "." with "[dot]" and "@" with "[at]". It's not the most ironclad protection, but it thwarts most casual eMail sniffers.

i modified the centering functions and created this which centers each word on it's own line. You can adjust the spacing with the $valign var. currently no implimentation if text is too large for image. strings are tokenized by space, but can obviously be changed.

Creates a box of text. Has horizontal and vertical alignment, box arguments, and custom leading. I submitted this to the manual in 2003 actually, but it disappeared after a year or so (not sure why). Here it is again.
